Three Rivers WWTP - Live Oak County, Texas Wastewater Treatment Plant

Three Rivers WWTP is a municipal wastewater treatment facility located in Live Oak County, Texas, United States. The plant serves a small community of approximately 1,925 people, reflecting its role in managing local wastewater in a rural setting. The plant operates with secondary treatment, which is the standard level required by the US Clean Water Act for most municipal facilities. Its designed capacity is 1,514.16 thousand cubic meters, and it currently treats an annual volume of 677.59 thousand cubic meters, indicating available capacity for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Gulf of Mexico via the Nueces River basin. The plant's inland location, over 50 km from the coast, reduces direct marine impact, but its discharge supports downstream aquatic ecosystems and water quality in the region.

The plant discharges into the Nueces River watershed, which flows southeast through Texas and empties into the Gulf of Mexico. This basin supports diverse aquatic life and provides water for agriculture and communities. The secondary treatment process helps reduce organic pollutants and suspended solids, protecting downstream water quality and habitat.
